We have reports that we use WINSCP to transfer to remote clients and had to change the fingerprint a couple months back. Ever since, two of the reports run successfully but the third always fails after transferring 32KB. In the session log you will see where the problem begins at 3:15.22.213. This is a recurring error every time, always after writing 37290 bytes, never more never less. This file usually ranges between 220KB to 230KB. I will also include the script that is used to run this task and it is automated using task scheduler. Thanks for your help
